FIG 4.

Metabolic potential of two GI variants. (A) Extra growth in medium amended with benzoate compared to benzoate-free medium as a percentage of the growth in benzoate-free medium. Error bars depict standard deviations of the results from two replicates. (B) Extra growth in medium amended with nitrate compared to nitrogen-depleted medium as a percentage of average extra growth in media amended with ammonia and urea, respectively, compared to nitrogen-depleted medium. Error bars depict standard deviations of the results from two replicates.
